COMBINED FILTER AND COOLER.

SPECIFICATION forming pari; of Letters Patent No. 308,058, dated November 18, 1884.-.

l Application lilell Juy 26, 18S-l. (No modell llo all 'whom t 77u11/ concern.-

Beit known that l, J AMES CARTER, of Lockport, in the county ot' Niagara and State of New York, have .invented certain new and useful Improvements in a Combined Filter and Cooler; and I do hereby declare t-hat the folowing description ot` my said invention, taken in connection with the accompanying sheet of drawings, forms atull, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My present invention has general reference to a combined water filter and cooler; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointedtout in the claims.

In the drawings, already referred to, which serve to illustrate my said invention more i'ully, Figure 1 is a side elevation of my improved combined water cooler and iilter. Fig. 2 is a longitudinal sectional elevation ot' the same. Fig. 3 is a plan in line 1/ y, and Fig. 4 a similar view -in linexx, of Fig-2. Fig. 5 is a transverse sectional elevation of a portion ot' the filter-water receptaol e, showing the construction of the sponge-cup. Fig. 6 isasimilar view of the false bottom for the ico-receptacle.

Like parts are designated by corresponding letters ot' reference in all the iigures.

The object of my present invention is the construction of a simple, convenient, and efficient combined water iilter and cooler in which the water resulting from the melting ot" the ice shall be kept separate from the filtered water, to prevent contamination of the latter in cases where impure ice is bei-ng used for cooling the filtered drinking water. To attain these results I construct my improved combined filter and cooler essentially of a cylindrical receptacle, A, having a bottoni, a, said cylinder A resting upon an enlarged jacket, B, having a base, C, provided with a diaphragm, D, serving as a bottom for the charcoal filling around the cylinder A, as clearly shown in Fig. 2.

Vithin the receptacle A, I place an ice-l receiver, E, consisting of a cylindrical receptacle having a bottom, E, said receiverE being sufficiently smaller than the outer cylininder, A, to produce an annular space, into which is placed the filter-water reservoir F, (shown on an enlarged scale in Fig. 2,) said reservoir consisting ot' an annular vessel having in its bottoni f; Fig. 5, two or more 1ozenge-shaped chambers, H, serving as spongecups, and at the same time as outlet-s from the filter-water reservoir F. In the upper concave of this tiltercup there is a large opening, 11, through which a sponge is introduced into the lozenge-shaped cup. and in thelower concave is a smaller outlet, It', through which the water passes to the iilter bed N, Fig. 2, below the filter-water reservoir, said outleth being made so much smaller that the sponge mentioned cannot be passed through it, either accidentally or otherwise. The edge around the aperture h in the filter-cup I-I is Wired, or rounded-ott' at h, so that the sponge may be readily withdrawn i'rom the cup whenever desired without tearing said sponge. This rounding ott at It also serves to directl the water through the center of the sponge, and prevents it from following theline ofthe metal.

The filterbed N consists of" the usual niaterials-viz., charcoal, tine and coarse gravel, placed in layers in the usual manner. It rests upon a perforated diaphragm placed into the receptacle A a suitable distance below the tilter-water reservoir-E, so as to leave in the lower portion of the receptacle A a space. S, Fig. 2, serving as a reservoir for the iiltered drinking-water, said receptacle A being provided with a boss, into which a faucet, G, is inserted, by means of which the drinking-Water is removed from the drinking-waterreservoir.

In the ice receiver E there is a similar faucet, G. by means of which the melted water from the ice is withdrawn from said ice-re ceiver E, the two faucets E E 'being placed side by side, (by preference,) as shown in Fig. 1.

V is a vent-passage leading from the drinking-water reservoir to the exterior of the vessel A upward as high as the said vessel A.

This vent-passage permits air to enter thev drinking-water reservoir whenever water is drawn from that chamber. The vessel A is closed by means of a removable iilled cover,

IOC

I, having a recess in its under side to admita second but smaller cover. K. plaeed onlo the iCe-reCeirer E, as clearly illustrated in Fig. l. Said vessel A is, furthermore, provided with a pair ot' handles, J, Fig. l, by means of which it Carried about.

ln operation, the water to be filtered and cooled for drinking purposes is poured into the lilter-water reservoir F. From here it passes through the sponge-cup II and the iilterbed N into the drin king-water reservoir S, from which itis withd raw n :1s occasion requires through the faucet G. Into the receiver E the ice is placed, and the water resulting from its melting` is collected within, and may be withdrawn from said receiver through the faucet G. It will thus be readily seen llrit the water resulting l'rom the melting` ot' the ice is not permitted to coinmingle with that passed through the iller, and that .thereby the oontamination ot' the filtered wat-er by impurities from the ice-water is etli'otually guarded y against.

The apparatus may be made from any snitable sheet metal, such as is now usually employed in the manufacture of water iltersand' coolers. and the various reservoirs eontaining the liquids may be covered with a vitrilied coating, (socallec porcelain-lined,) if de- Sired, in the now well-.known manner.

A combined filter and Cooler substantially as hereinbefore deseribed may be manufactured and sold Y as cheaply as any other lirstclass article ol" the class mentioned` and the construction of tbesponge-eup may be readily applied to other tilters, it' desired.

To prevent the ice when placed into the ieereceiver E from damaging1 the bottom of' the said receiver I place into the said :receiver an auxiliary bottomA L, consisting of a convex disk, L, Fig. 6. This convex plate receives the blows from the ice, and it' indented therefrom to such an extent as to render its further use undesirable may be readily replaced by a new one at a trifling Lxpense. Thic auxiliary bottom is quie n essential appendage to my water filter and cooler, inasmu'h as it prevents both the indenting (and thereby de2 strnetio" oft le eereeeiver and the chipp'rg oft' ot' the vitriiied lining" of said reservoir. lt

is stiiened by means of cross-wires on the concave side, as M as shown in Fig. 6, and with a linger-hole N, to enable is removal from' the ieereceptaele E.

I'I-.iving thus fully described myl invention, I claim as new. and desire to secure to me by dLetters Patent ol' the United Statesl. A combined filter and water-coder, consisting.\essentiull v, ot` an outer reeertaele, A. having centrally a.. ice-receiver extending the entirel depth ot' the structure, an annular ring-shaped removable lilter waterreservoir. F, surrouinling said ice-receiver E, the iilterbed N, and the drinking-water reservoir S, s id ice-reeepial'lle being removably inserted, substantially as and for the object stated. i

2. ln combination with the drinking-water reservoir S, the superimposed filter-bed N, and the filter-water reservoir F, said drinking, water reservoir being provided with the vent-tube V. as deseribed.

o. In water-filters, a spongeeup consisting of a lozenge-shaped vessel. H, inserted into or secured to the bottoni of the filter-water reservoir F, said vessel H having the ingressopening h with the rounded edge It, and the egress-passage lt, as and for the object specified.

et. In an ice-Watercooler, the combination, with the ice-receiver, ot'an auxiliary removable bot om. I, consisting oi' a eoncavoeonvex disk having the convex side uppermost and the eoneave side provided with .he re-enforc ing crosswires, as and l'or the object slated.

5. In water iilters and coolers. a filter-water pan consisting of an annular ringshaped receptacle removably resting with its upper edge n pon the npper edge ofthe receptacle A, and having in its bottom the sponge-oups H, as described, with the ieereeeiver within the ringsliaped receptacle E. as specited.

In testimony that I claim the foregoing as my invention I have hereto set my hand in the presence of' two subscribing witnesses.
